From: Polarization dependence of second harmonic generation from plasmonic nanoprism arrays

Spectral (a) and polarization (b) dependences of the SHG signal. Fundamental intensity dependence of SHG signal for polarization angles corresponding to (c) a maximum, 30°, and (d) a minimum, 0° in this case. The dashed lines in (c,d) represent quadratic power dependence fits to the data.
